Classification Of A Meteorite Found Near Colgate, North Dakota, Justin Germann
Classification Of A Meteorite Found Near Colgate, North Dakota, Justin Germann
Undergraduate Theses and Senior Projects
In 1999 a 39 Kg stony meteorite was found near Colgate, North Dakota, during the construction of a new house. The surface of the meteorite contains many shallow regmaglypts and a weathered crust with a reddish orange color to dark brown-red, and the interior reveals a high abundance of metallic flecks. The SiO2/MgO ratio is 1.5, FeO/SiO2 ratio is 0.71, the Femetallic/FeO ratio is 0.72, the total metallic Fe is 19.8%,the average chondrule diameter is 0.3 mm, and the Fa composition is 20.27 mol%. The meteorite also has a crystalline matrix, with mostly well segregated chondrules, little igneous glass, and …
Gödel’S Incompleteness Theorem, Emma Buntrock
Gödel’S Incompleteness Theorem, Emma Buntrock
Essential Studies UNDergraduate Showcase
In 1931 Gödel released his Incompleteness Theorem. His theorem was the opposite of what other mathematicians at the time wanted, but it was very influential to realize there is no perfectly complete formal systems. The incompleteness theorem is based of the idea that in a consistent system there are pieces that can not be proved or disproved, causing for incompleteness. The second part of that idea is that such a system can not prove that itself is consistent, which also makes it incomplete. I will verify theses proofs using a series of logic problems that show how a system is …

As a prospective math educator who will be teaching in the near future, I was concerned with the idea of preparing my future students for college math courses. I decided to research the effects of teaching students how to appropriately use problem solving strategies in math. My research led me towards looking at the benefits of students becoming better problem solvers and how teachers can implement problem solving into their daily lessons.
When this implementation is successful, students can become more independent with their learning, they are able to work and persevere through challenging problems, and they have a greater …
The Most Important Statistics In Football, Jacob Holmen
The Most Important Statistics In Football, Jacob Holmen
Essential Studies UNDergraduate Showcase
This research is based on the Five Factors that were devised by Bill Connelly of SBNation. The Five Factors of football include Explosiveness, Efficiency, Field Position, Finishing Drives, and Turnovers. Each factor is composed of associated statistics that when put together make up the most important statistics in football. This research includes the analysis of all 857 FBS (the highest level of NCAA Division I football) games from the 2016 season. Data was analyzed through the use of an Excel spreadsheet. Five different statistics were looked at, each associated with one of the Five Factors. The statistics include Yards per …

Major League Baseball has been a catalyst for making decisions in sports and competition from a purely mathematical viewpoint. We have seen teams utilize unique on-field player alignments and roster-building strategies based on statistical observations and applications of math. This project examines the advantages Sabermetrics and analytics present within the sport. Untapped statistical categories that could further the success of teams in the future is also briefly discussed.

We report a combined experimental and theoretical study of the growth of sub-monolayer amounts of silicon (Si) on molybdenum disulfide (MoS2). At room temperature and low deposition rates we have found compelling evidence that the deposited Si atoms intercalate between the MoS2 layers. Our evidence relies on several experimental observations: (1) Upon the deposition of Si on pristine MoS2 the morphology of the surface transforms from a smooth surface to a hill-and-valley surface. The lattice constant of the hill-and-valley structure amounts to 3.16 Å, which is exactly the lattice constant of pristine MoS2. (2) The transitions from hills to valleys …

Results from 20 samples showed that supercritical CO2 enables extraction of a considerable portion (15%–65%) of the hydrocarbons from the Bakken shales within 24 hours. The results may be used to improve modeling and forecasting the effects of CO2 enhanced oil recovery (EOR) and suggest the possibility for increasing ultimate recovery, and possibly CO2 storage, in some areas of the Bakken Formation.

Nest predation is a critical component in avian productivity and typically is the leading cause of nest failure for most birds. Several landscape features are thought to drive the behavioral interaction between northern bobwhite (Colinus virginianus; e.g., nest placement) and their predators (e.g., search methods for food acquisition). In order to understand habitat characteristics influencing predation, we studied bobwhite nests using 24-hour near-infrared video cameras. We monitored 675 bobwhite nests with cameras on 3 properties in northern Florida and southern Georgia, USA, during 2000–2006. To test the association between nest failures and specific failure causes with landscape structure, we calculated …
